Being subject to constant noise on your automobile tends to be irritating, a automobile is so elaborate that it is usually difficult to find its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Audi S4, we will almost certainly be able to help you. Indeed, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Audi S4. This is why, firstly, we will check out what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the sources of clicking noise on Audi S4 coming from your suspensions.
I perceive a clicking noise on Audi S4 from my engine
Verify your high engine
If you perceive a clicking noise on Audi S4, and this noise is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Audi S4. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this situation, remember to change them.
Verify your low engine
If you have identified the region of source of the Audi S4 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both cases, the risk in the long term is the breakage of the motor. These two maintenance are very difficult and most mechanics will advise you to swap the engine of your Audi S4.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi S4 is connected to the combustion of your engine, there are three possible reasons of it. Verify the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible that your timing belt is shifted and that it does not properly manage the timing of the various engine components to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are destroyed. In this circumstance, do not hesitate to check this content page which deals in detail with the different injection sounds on Audi S4.
I perceive a clicking noise on Audi S4 in my direction
Verify the condition of the gimbals
One of the most common causes of a clicking noises in the direction of your Audi S4 is related to the direction of the automobile. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can generate a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be changed very quickly, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it. If you would like more detailed information about gimbals noises on Audi S4, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you know a clicking noise on your Audi S4, it is plausible that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the circumstance, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I perceive a clicking noise on Audi S4 coming from my suspensions
Verify the suspension
If you encounter a clicking noise on your Audi S4 once you pass a speed bump, it is extremely plausible that your suspension block is the cause of the noise. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To examine if this is the trouble that concerns you, take a dented road and, at low speed, focus on the noise originating from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you are subject to a clicking noise on your Audi S4 at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a explanation. To examine the state of the spring, position the automobile on a flat surface and measure that the heights from the ground to the bottom of the body are identical on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too large it denotes that most likely your springs are worn, if you find out a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, make sure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on Audi S4 than a clicking noise, don’t hesitate to consult this article.
